> essentially all L2 systems require 2 tx on L1. True. But once an L2 channel is anchored on L1 using those 2 L1 transactions it can support an unlimited number of L2 transactions, they take milliseconds to do, and an unlimited number can happen in parallel - all without any more L1 transactions. L1's main use is to become the place L2 channels are created. Creating 7 entire channels per second sounds like it should be more than enough.
